A good one! File order on USB pen drive

Here’s a good one – a million cred points to anyone out there that knows the answer to this one! I have a FM modulator that plays MP3 files on the inserted USB pen drive in the order they are on the drive. I want them to play in a particular order and therefore need to put them on in that order but of course in Windows I can see them in name, size, etc order but not in the raw file order. Any ideas about how I can see what order they are stored on the drive and reorder them so that they play in the right order? Thanks!
